A framework of complementary behavior has been proposed which maintains that direct-manipulation and speech interfaces have reciprocal strengths and weaknesses. This suggests that user interface performance and acceptance may increase by adopting a multimodal approach that combines speech and direct manipulation. This effort examined the hypothesis that the(More)
The purpose of this study was to identify trends in the utilization and acceptance of handheld computers (personal digital assistants) among medical students during preclinical and clinical training. We surveyed 366 medical students and collected information on computer expertise, current handheld computer use, predicted future use, and user acceptance.(More)
As the healthcare industry continues to become more distributed, healthcare organizations are increasing their reliance on mobile links to access patient information and to update their master database at the point of care. Handheld computers have evolved into a viable platform for these systems. While initial projects have shown promise, several questions(More)
The Rural Cancer Outreach Program (RCOP) between two rural hospitals and the Medical College of Virginia's Massey Cancer Center (MCC) was developed to bring state-of-the-art cancer care to medically underserved rural patients. The financial impact of the RCOP on both the rural hospitals and the MCC was analyzed. Pre- and post-RCOP financial data were(More)
A model of complimentary behavior has been suggested based on arguments that direct manipulation and speech recognition interfaces have complimentary strengths and weaknesses. Specifically, anecdotal arguments have been given that direct manipulation interfaces are best used for specifying simple actions when all references are visible and the number of(More)
Speech interfaces have the potential to address the data entry bottleneck of many applications is the field of medical informatics. An experimental study evaluated the effect of perceptual structure on a multimodal speech interface for the collection of histopathology data. A perceptually structured multimodal interface, using speech and direct(More)
